Patent ES-343174-A1 (ES)
Title: Electromagnetic superconducting accumulator device and method for accumulating electrical energy
IPC: H01L39/14
Filed: 1967-07-19
Abstract: A moving magnetic field is provided in the vicinity of a thin foil closed-loop superconductor circuit to enable magnetic flux to become accumulated in the loop, and a second circuit is associated with the superconductor circuit so that the energy accumulated in the superconductor circuit may, when required, be released into the second circuit. In the form shown, the superconductor circuit comprises a cylindrical sheet 11 covered with insulating material 30. A series of coils 1-6 are supplied from a multi-phase supply using a circuit producing a magnetic field which progresses in overlapping pulses parallel to the axis of the sheet 11, inducing moving localized zones of normal conduction in the sheet 11 and thereby permitting flux lines to be introduced into the central space enclosed by the sheet 11. Localized heating synchronized with the movement of the field provided by the coils 1-6 may also be employed to produce the moving zone of normal conduction. In order to release the energy from the sheet 11 current is passed through a conducting strip 31 toroidally wound around the sheet 11, and the Joule heating produced in the strip 31 causes the entire sheet 11 to become normally conducting, thereby releasing its accumulated energy to the energyreceiving circuit which comprises a helical strip 36. The sheet 11 and strips 31 and 36 may all be enclosed within a cylindrical insulating mass 37. The strip 36 may alternatively be mounted outside the superconducting cylinder 11, and may form a separate assembly. The superconducting circuit may comprise a series of mutually insulated coaxial cylindrical sheets such as 11, or may have a toroidal form in which case the coils providing the moving magnetic field may be mounted in or perpendicularly to the plane of symmetry of the torus. Anisotropic superconducting sheets providing a preferential direction of current flow may also be used.

Title: Improvements in or relating to Push-Button Tuning Mechanisms
IPC: H03J5/12
Filed: 1967-08-11
Abstract: In a push-button tuner each button has a member which moves through a given distance and engages a second member, one of the members having a plurality of abutments spaced angularly about an axis and longitudinally with respect to the axis one member is angularly adjustable and has a portion of regular polygonal shape which slidably engages a corresponding aperture to lock the member in a predetermined angular position and hence determine which abutment engages the other member. Fig. 1 shows one button of a television receiver in which the selection of the appropriate abutment automatically sets the wave-band and line-frequency standard for the station corresponding to that button. The button spindle 2 carries a nut 7 which operates a lever 8 for setting the tuning means in the usual way, the nut being axially adjustable by rotation of the button. The nut is preferably of plastic which grips the spindle to reduce the risk of accidental detuning. At the rear of the receiver the button shaft is polygonal and ends in a knob 37, the polygonal section carrying at its end a semi-circular rib 31. One abutment is formed by the surface of the rib at 31a and other abutments are formed by the ends of rods 28, 29, 30 projecting from the rib to unequal extents. These four abutments correspond, e.g. to four wavebands operating on 405 lines. Similarly (as seen in Fig. 2, not shown) there are three rods (32, 33, 34) on the opposite side of the axis which together with the other end (31b) of the rib 31 form four abutments corresponding to four wavebands operating on 625 lines. When the button is pressed in, one of these eight abutments will engage a spring-loaded switch bar, 17 common to all the buttons and move it through the appropriate distance to select the correct waveband for that button. The upper edge of the bar 17 has a pin-and-slot connection 25a with a bell-crank 25 pivoted at 23 and operating the waveband switch (not shown) through a pin 27. The line-frequency switch is operated through a plate 43 which slides transversely to the button spindle and is biased to one extreme position or the other. With no button pressed, a ridge 46 is urged upwards into the position shown, and will remain so if the button is adjusted to a 405-waveband. On the 605- wavebands the rib 31 will engage the ridge 46 and depress it, causing the other end 44 to operate the line-standard switch (not shown). If a second 605-button is now pressed, the rib 31 will hold the ridge 46 down before the latching mechanism 13, 14 releases the first button. For a single-system receiver only one set of abutments is provided on each button and the mechanism 43, 44, 46 is omitted. Adjustment of abutments.-The knob 37 is pushed in until its polygonal portion 35 becomes disengaged from the corresponding aperture 36 in the wall of the housing. The knob is then rotated to bring the appropriate abutment opposite the switch bar 17. On release, the knob is returned to its original position by a bifurcated leaf spring 42.

Title: A system of electronic ignition with incorporated advance
IPC: F02P3/00
Filed: 1967-10-21
Abstract: An ignition system for an internal-combustion engine comprises a saturable core converter 1 producing a rectified and filtered output, an ignition unit 2 comprising an ignition coil 24, a resonant circuit receiving the output of the converter to produce a charging current for the ignition coil, a triggered electronic switch 2 to control passage of the charging current for the ignition coil and a pulse generator 3 inductively controlled by the magnetic flux produced by a make and break device (not shown) of a magnetic circuit of an electromagnet to provide a triggering pulse to the switch each time a spark is required. The magnetic make and break device is adapted to be driven by the engine and is such that as the engine speed varies the time taken by the magnetic make and break device to make the magnetic circuit and establish therein a flux such as to cause the pulse generator to produce a triggering varies so that as the engine speed increases the ignition is automatically advanced and as the engine speed decreases the ignition is automatically retarded. The condenser 23 is connected to discharge into the ignition coil 24 using a silicon controlled diode 21 as the switch.

Title: Diehead for plastic extrusion machines
IPC: B29C48/09
Filed: 1967-12-20
Abstract: During the extrusion of plastics tubing, in particular when associated with blow-moulding operations, nozzle end 40a, Fig. 3, of die head 35 is adjusted laterally with respect to mandrel 17 by the movement in the same direction of a pair of rods 42a, 42b, or by the movement of a second pair of such rods (not shown) in the same plane and at right angles to the first pair. Normally such adjustments of nozzle end 40a are'made to ensure the issuance of uniform thickness extrudate from orifice 46. As shown, rods 42a, 42b are moved by simultaneous rotation of spindle nuts 29a, 29b, interconnected by chain 33, with consequential movement of spindles 37a, 37b upwards and downwards, respectively, as determined by threading 38a, 38b, and similar axial movement of wedges 39a, 39b connected to the spindles. The second pair of rods is moved on rotation of spindle nuts 30a, 30b, Fig. 4. In the embodiment of Figs. 5, 6 (not shown), manual adjustment tool 45 is replaced by a pair of reversible electric motors (48a, 48b). A modification of this embodiment, Figs. 11, 12 (not shown), employs a single motor (96), electrically, hydraulically or pneumatically operated, which drives sprockets (99, 100) by means of chain (98). Sprockets (99, 100) are respectively connected to sprockets (125a, 126a) by chains (133, 132) and a clutch mechanism (103, 105, 107), Fig. 11 (not shown), driven by an hydraulic or pneumatic double-acting servomotor (115) brings either spindles (128, 128a) or (129, 129a) into rotation depending as clutch lever (107) is rotated about pivot (106) to bring clutch member (103) into engagement with spindle nut (123) or clutch member (105) into engagement with spindle nut (124). In the embodiment of Figs. 7, 8 (not shown), rods (64) are connected to the pistons (63) of two pairs of double-acting hydraulic cylinders (58a, 58b) and (59a, 59b). As before, the nozzle end is moved by movement in the same direction of one or other of the rod pairs. In a further modification, Fig. 9, 10 (not shown), the chain and sprocket arrangement 33, 34 &c. of Figs. 3 and 4 is replaced by gears (81a, 81b, 82a, 82b) or gear segments (87). Also the sprockets (97, 99, 100), Figs. 11, 12 (not shown), may be replaced by gears. In a final embodiment, Figs. 13, 14 (not shown), a multiplex die head comprises nozzle ends (140a, 140b, 140c &c.), and a single motor (137) drives gears (152, 152a, 152b &c.) to rotate, as required, clutches (150). Each clutch (150) may be brought by coaxial movement into engagement with a gear (153) to rotate one spindle pair or a gear (154) to rotate the other spindle pair. To further regulate the material flow, an axially reciprocable sleeve (79), Fig. 7 (not shown), may be incorporated in the die head. A nut (134), Fig. 11 (not shown), is rotatable on mandrel support (135) to move such a sleeve.

Title: Differential shrinkage yarn
IPC: D01F6/60
Filed: 1968-01-05
Abstract: A yarn comprises a plurality of continuous oriented polyamide filaments of two types having a difference in filament length of at least 1% when subjected to boiling water under a load of 4 milligrams per denier, the difference increasing by at least 0À5% when the filaments are further subjected to heat setting for two minutes under a similar load, each filament containing at least 50 mole per cent of repeating units of the formula where each of the R radicals which may be the same or different is H or CH 3 , x is 1 or 2, and y is an integer from 7 to 14 inclusive. In examples the diamine used was bis-(4-aminocyclohexyl)- methane, and the acid was one with y = 7, 10, or 14. In the preferred embodiment one type of filaments consist essentially of a polyamide having units of the formula while the other filaments comprise a copolyamide having 50-95 mole per cent of the units of the formula and the remaining percentage of units having a different diamine-for example m- and p-xylylene diamine 1,4-aminomethylcyclohexane and other aliphatic, aromatic or cycloaliphatic diamines- or a different dicarboxylic acid-for example iso- and tere-phthalic acid, 1,4-cyclohexyl dicarboxylic, and aliphatic dicarboxylic acids containing 6-16 carbon atoms. Alternatively all the filaments may be of this copolyamide but with one type of filament having 5 mole per cent more of the units of the formula than the other type or all the filaments may be composed essentially of the units of the formula with the two types of filaments having (a) different numbers of trans-trans, cis-trans, and cic-cis diamino units in the polymer, (b) different relative viscosities, (c) different chain length in the diacid constituent, or (d) orientation indices differing by at least 1À0 (as by being drawn at different temperatures or by varying the filament denier or conditions at extrusion or quenching). The two types of filaments may differ in a plurality of the above ways. The filaments may contain antistatic agents-e.g. nonylphenoxy capped polyethylene ether alcohol-heat and light stabilizers, antioxidants, ultraviolet light absorbers, delustrants, pigments, dyes, and additives to improve dyeability, soil repellence, crease resistance, hand, water repellence, wickability, strength, elongation, elastic modulus, static propensity, or melting point. The two types of filaments may be spun from the same or different spinnerets and have a round, multilobal or shield shape. They may be intermingled by an air jet. The filaments may be hot-i.e. 140-180 C.-or cold drawn, and be heat relaxed after drawing to achieve the desired shrinkage in boiling water. The yarn is bulked, when woven or knitted, by being shrunk in a hot scouring operation while relaxed, or by being cold and/or high tension scoured and then heat set under low tension.
